Data queries

We just heard about "Data Queries," but what are they? A data query is a special way of retrieving indexed data such as a list of network interfaces or running processes on a Linux server. It consists of an XML file defining the location of the data to be retrieved and the actual method for retrieving it. In addition to the XML file, a data query also needs to be defined in Cacti in order for Cacti to map the data to an associated graph template.
